| 中文摘要: |
| 对电感耦合等离子体质谱法(ICP-MS法)测定高纯黄金中铅含量的测量不确定度进行了评定。对试料的称重、标准溶液的配制、工作曲线的拟合、测量重复性的各分量的不确定度进行分析与计算，通过合成得到测量结果的合成不确定度与扩展不确定度。 |
| 英文摘要: |
| The uncertainty of quantitative determination of lead in fine gold by inductively coupled plasma mass spectrometry (ICP-MS) was evaluated. The impacts of major sources of uncertainty were discussed and calculated, such as weighing, standard solution, standard curve and measurement repeatability. Both of the combined uncertainty and the expanded uncertainty were also obtained by combining every calculated components of uncertainty. |
